Hardware Verification

Concept

Hardware verification is the set of techniques used to check hardware designs through simulation, test generation, model-checking representations, and analysis workflows. In the provided evidence, it is characterized especially by constrained-random simulation for stimulus generation, automated ISS-oriented test-suite generation, standardized formats such as Btor2 and Btor2MLIR for hardware model checking, and emerging graph-based methods for gate-level netlist verification.
